| Abstract: |
| A method to measure magnetic field around conductor to calculate current in finite rectangle conductor was put forward based on Biot-Savart law. The triple integral model for a precise calculation of magnetic induction intensity around the conductor was established by MATLAB simulation and the simplified analysis formula of shape factor was obtained by fitting data. A method to eliminate interference fields was proposed, the mathematical expressions were provided, and the anode current calculation model for aluminum reduction cell was derived. The feasibility of this method in real-time monitoring of anode current distribution is verified by both theoretical verification and field measurements analysis. |
